New technique builds super-hard metals from nanoparticles

Providence RI (SPX) Jan 25, 2021
Metallurgists have all kinds of ways to make a chunk of metal harder. They can bend it, twist it, run it between two rollers or pound it with a hammer. These methods work by breaking up the metal’s grain structure – the microscopic crystalline domains that form a bulk piece of metal. Smaller grains make for harder metals. Now, a group of Brown University researchers has found a way to cust Source: NanoDaily.com New technique builds super-hard metals from nanoparticles
